' Fry 6 27 NITED STATES PAENT DAVID R. PBOCTOR, OF CHICAGO, ILLINOIS, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO THE GLOBE SECTIONAL HEAD COMPANY,

OF SAME PLACE.

BARREL-HEAD.

SPECIFICATION forming part of Letters Patent No. 392,570, dated November 6, 1888.

Application filed March 12, 1888. Serial No. 267,049. (ModeL) To all whom it may concern.-

Be it known that I, DAVID R. PROOTOR, of Chicago, county of Cook, and State of Illinois, have invented certain Improvements in Barrels, of which the following is a specification.

My invention relates to the construction of abarrel-head and the arrangement of its parts in such a manner that the head can be removed and then replaced again without removing or disturbing the hoops upon the barrel, and doing this in a cheap, expeditious, and secure manner.

My said invention will be hereinafter more fully described with reference to the accompanying drawings, in which-- Figure 1 represents a perspective of a portion of a barrel with a head in it embracing in its construction and arrangement of parts my said improvement; Fig. 2, a like view of the head of a barrel, the parts being detached in order to display the construction of the same; Fig. 3, a transverse vertical section of the two principal sections 13 and O of the head and the two keys D and E in position, made as indicated by the broken line 00 x in Fig.1; Figs. 4 and 5,detail views in perspective of the keys D and E; and Figs. 6 and 7, detail views of parts, all the detail Views, including Fig. 3, on an enlarged scale.

The principal sections 13 and C of the head are each of the same forms and dimensions. Their inner edges are cut away, so as to form V-shaped grooves, into which fit snugly corresponding formations on the side edges of keys D and 1], as shown in Fig. 3. They are also cut away on their faces, so as to form ledges b and c on their upper sides at one end and other exactly similar ledges, b c',on their other ends on their under sides, as shown by the brokenlines in Fig. 2. These ledges, being triangular in their surface, form and are designed to afford proper bearing-surfaces for the wide ends or butts of the keys.

The keys D and E have exactly the same form and dimensions. Their outer ends are beveled to fit into the grooves in the staves made by the croze just as the principal sec tions of the head are. The upper surface of the key E is cut away from itsbutt or wide end back to within afew inches of its narrow end, where it is left with its full thickness,as shown at e in Fig. 4., in order that it may stand out flush with the headsections, and thus have its full form and strength preserved at that end. The under surface of the key D is cut awayin a manner that is exactly similar for the same purpose, as shown in Fig. 5, and each has its side edges cut away correspondingly in order to form tongues d and e, to fit snugly within the grooves in the side edges of the head-sections B and C, and to form shoulders (1* and e to rest against the head-sections, as hereinbefore specified. The butts or broad ends of the keys overlap each other lengthwise for a few inches and still leave spaces long enough as well as wide enough above and below each key for all requisite endwise motion of each when forced in or out of position for the purpose of closing or opening the head.

The endwise lap of the butts of the two keys is long enough to make thcjoints between the two parts fluid-tight, especially when they are drawn together by the screw F. The joints thus made between the side edges of the headsections and the side edges of the keys are especially tight and strong, because in addition to the tonguc-andgroove construction hereinbefore specified the edges of the keys-z'.. 0., the shoulders 01 eextend over and fit down upon the upper and lower surfaces, respectively, of the two head sections; and, moreover, the tongue-and-groovc formations can be forced into close contact by reason of the wedge-like form of the keys and their being capable of being driven, by blows against their butt-ends as well as their outer ends, fully home into the croze.

In Fig. l the barrelis shown as closed, and a screw,F, which extends through key D down into key E, is used to prevent the two keys having lengthwise motion upon each other in case of any jars or strains upon the side ends of the barrel. In order to open the head, that screw must be removed, and by any suitable tool inserted in the hole (1 the keyD can be forced endwise from the croze, and then the key E is removed in a similar manner. The

head-sections can then be easily. taken out.

To close it again,the key E is driven into position between the headsections, and then the key D likewise, and then the screw F is turned in.

By reason of the facility with which this improved head can be opened and closed and the tightness of all the joints made between the keys themselves and between them and the head-sections, wasting and smearing of the contents of the barrel are efiectually prevented in case the barrel should contain pickle, sirup, or 0il,which would be uncleanly and offensive.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A barrel-head composed of sections having grooves in their inner edges and two keys, D and E,the edges of which incline from their inner to their outer ends and present, when their butts are overlapped, tongue formations to correspond with the grooves in the headsections, and are capable of being driven endwise from their butts to make tight joints with the sections and with the croze in the staves at their narrow ends, substantially as described.

2. The described head-sections B and C,cut away to form ledges b and c in their upper sides at one end and on their lower sides at the other end, in combination with the keys D and E, the upper and lower surfaces, respeotively, being cut down from their buttends to near their small ends, on which are left the parts 6 and d of full thickness,adapted to secure strength at their narrow ends and play-room for endwise motion of the keys upon each other, substantially as described.

3. In combination with the described keys D and E, the butts of which are overlapped one upon the other, the screw-hole (1 through both keys, and the screw F, adapted to lock together and unlock the butts, substantially as described.

DAVID R. PROOTOR.
